Commands for Managing the Switch
ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
ExtremeWare XOS 11.5 Command Reference Guide
116
configure power supply
configure power supply <ps_num> {auto | on}
Description
Configures a power supply for either automatic power management, or forced on, regardless of the
impact to the total available system power.
Syntax Description
Default
The default setting is auto; ExtremeWare XOS either enables or disables the PSU in order to maximize
total system power.
Usage Guidelines
If a switch has PSUs with a mix of both 220V AC and 110V AC inputs, ExtremeWare XOS maximizes
system power by automatically taking one of two possible actions:
●
If all PSUs are enabled then all PSUs must be budgeted at 110V AC to prevent overload of PSUs
with 110V AC inputs.
OR
●
If the PSUs with 110V AC inputs are disabled, then the PSUs with 220V AC inputs can be budgeted
with a higher output per PSU.
ExtremeWare XOS computes the total available power using both methods and automatically uses the
PSU configuration that provides the greatest amount of power to the switch.
Table 10
lists combinations
where ExtremeWare XOS maximizes system power by disabling the PSUs with 110V AC inputs.
ps_num
Specifies the slot number of the installed power supply unit (PSU) to which
this command applies.
auto
Specifies that ExtremeWare XOS determines the enabled or disabled state of
the PSU to maximize total system power. This is the default.
on
Specifies that the PSU be enabled even if ExtremeWare XOS determines it
should be disabled. This action may reduce the total available system power
and may result in one or more I/O modules powering down.
